Virtual box White Rectangle

Post by Demiurgod »

Hello, I am using a virtual machine, yesterday I do not know what I touched or what I did but now I have a white rectangle on the right side of my screen. I can't do anything in this rectangle and it takes away space on my screen, any suggestions ? Thank you very much, have a nice day.

Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

Moving to Linux Guests, now that we know what the VM's OS is.

A couple of things can be done to make the VM work better, though I'm not certain they will fix the problem.

Synchronize Virtualbox and the Extension Pack; the versions should match:
00:00:01.982548 VirtualBox VM 6.1.28 r147628 win.amd64 (Oct 18 2021 18:49:03) release log
00:00:02.029684 Installed Extension Packs:
00:00:02.030092 Oracle VM VirtualBox Extension Pack (Version: 6.1.30 r148432; VRDE Module: VBoxVRDP)
Give the VM two processors:
00:00:02.687146 CPUM: Physical host cores: 8
00:00:02.687429 Full Name: "AMD Ryzen 7 3800X 8-Core Processor "
Guest CPU settings:
00:00:02.134792 NumCPUs <integer> = 0x0000000000000001 (1)
Increase VM RAM to 2GB and maximize video RAM:
00:00:02.029069 Host RAM: 16283MB (15.9GB) total, 6959MB (6.7GB) available
00:00:02.134794 RamSize <integer> = 0x0000000040000000 (1 073 741 824, 1 024 MB)
00:00:02.134979 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)
Guest Additions is installed, which is good. They're a few versions back, 6.1.18, but that often doesn't cause trouble unless a new feature or 3D acceleration is being used, and you have 3D off.

I see a few screen size changes in the log, otherwise no 'hardware' issues. The VM environment seems to be working fine.

This could be a failure in the VM's OS. It does happen. Try make a new VM of the same ISO, see if that one works OK. If it does, the VM's OS has probably got broken. Did the VM's disk possibly fill up?
